The one thing that really annoys me is that they don't have a keyboard shortcut for adding a new row. Now I always have to

1) Shift space to select the current row

2) Press the "right-click" button the keyboard

3) Press the down arrow 4 times to select "Insert 1 above"

4) Press enter

Or else I've to use the mouse, which is equally slow. It's really silly given that how often people insert rows.
